Detailed Description

template<typename Real, unsigned int N>
class sofa::helper::Monomial_LD< Real, N >

A generic monomial with N variables of type Real. A monomial is one term of a polynomial.

Todo this first version of polynomial is a linear presentation. This presentation is efficient for arithmetic operator like +,-,*,/ and derivative. But is not optimized for the evaluating (comparing to the recurrent presentation).
